WASTE-PIPE AND VALVE FORBASINS.

SPECIFICATION forming part of Letters Patmt No. 358,147, dated February 22, 1887.

Application filed October 2, 1886. Serial No. ll5,114. (No model.)

.To @ZZ whom it may concern:

Be it known that I, JOHN Dnirnnns'r, of the city and State of New York, have invented an Improvement in faste-Pipes and Valves for Basins, of which the following is a specitication.

Vaste-pipes for basins have been made with a valve and standing overflow-pipe at the junction of the waste-pipe that passes off from the bottom of the basin with the vertical pipe containing the valve and overliow, and this vertical pipe has passed through the marble slab supporting the basin;` but with these de.- vices difiieulty has arisen in consequence of the distance between the central outlet at the bottom ofthe basin and the opening through the slab varying by inaccuracy of workmanship orjdifferences in the size ol' the basin.

My present improvements are made with reference to adapting the horizontal wastepipe to different sizes of basins, and to adapting the vertical stand-pipe to differences in the thickness of the marble slab, or to differences in the depth of the basin; and I also provide for adjusting the cap upon the overiiow-pipe to suit the differences that arise in applying the other parts of the wastepipe to the basin.

In the drawings, Figure l is a vertical scction of the basin and the waste-pipe and valve connected therewith, and a part of the marble slab; and Fig. 2 is a section ot' the stand-pipe at right angles to Fig. l, and an elevation of the valve and overiow-pipe.

. The basin A is of suitable size and shape, and it is attached beneath the slab B in any ordinary manner. G is the horizontal portion of the wastepipe. D is the coupling for the sewer-pipe, and E the vertical portion or stand-pipe passing up through the slab.

The ferrule 3 of the strainer 2 passes through the bottom opening in thebasin A and screws into the bend of the horizontal waste-pipe O, as'usual. This waste-pipe C, instead of being of a iixed length, is variable to suit the differ-- ences that arise in consequence of differences in the diameter of the basin A and differences that arise from inaccuracy in the location of the hole that passes through the slab B and receives the upper end of the standing pipe The pipe O is made in two parts, connected together by the screw-coupling ri ug 4, and the portion 5 of one part of thepipe C, which goes through the coupling 4, is turned oit' on the outside to form a smooth` cylinder, and there is a rubber washer, 6, and a metal ring, 7, within the screw-coupling 4, so that after the parts have been'properly positioned the pipe C is. 11i/ade water-tight by screwing up the coupling-ring 4L and compressing the rubber ring 6 tightly around the smooth part 5 ofthe pipe.

.At the upper end of thestand-pipe E is the screwsocket G, that passes through the slab B, and it is provided with a ange, 7, resting upon the said slab, andthis socket G screws upon the outside of the stand-pipe E and supports the same iirmly in place.

In most instances the basin A is made with a horn or overflow, H, and the same is often longer in one basin than in another. I provide for connecting the lower end of this horn H to the pipe O by the thimble K having a tlarin g upper end for the reception of the horn and the cement or other packing material, and this thimble K passes through the screwcoupling l() upon the upper end of the branch pipe 11, above the waste-pipe O, and there is a rubber ring, 12, and metal ring 13 within the coupling-ring 10, that make the joint around the thimble Ktight; but this thimble K can be raised or lowered to adapt the sanne to the size and location ofthe horn H.

When there is not any horn H upon the basin A, the branch pipe 1l will be dispensed with; or the end of said branch pipe may be tightly closed by a disk of rubber or metal within the couplingring 10.

The overflowpipe M is provided with a valve, N, near its lower end, and with overiiow-holes l5, similar to the overflow-pipes heretofore made use of, and there is a cap, P, that is tubular, to pass into the socket G and screw upon the exterior of the overflow-pipe M, and in order to iirmly connect the overflow-pipe andthe cap after the parts have been properly placed I make use of the 1ocknut 16 around the overtlow-pipe M and set up tightly against the lower end of the tubular cap P. This allows of an adjustment to adapt the length of the overfiowpipe and cap to the distance from the top of the slab to the IOO valve-scat and compensate for differences in thickness of the slab.

In the interior of the socket G apin, 17, projects, and the tubular cap P is slotted, as seenin Fig. 2. The vertical portion 2() of this slot allows the cap, the overliow-pipc, and the valve to be lifted up in discharging the contents of the basin through the pipe C, and

when the cap P is partially turned the horizontal portion 27 of the slot receives the pin 17, and the valve is sustained thereby. TWhen the cap P is tnrncd so that the slot 28 receives the pin 17, the cap, the overflow-pipe, and the valve can be lifted out for cleaning, and should there be any obstruction in the pipes C or D the same may be removed by a plunger introduced into the stand-pipe E and niovcd up or down, siinilar to a syringe.

I claim as my invention- 1. The combination, with the stand-pipe E, passing up through the slab and the basin A, of a horizontal Waste-pipe, C, from the basin to the stand-pipe, and having a lateral branch,

11, the thinible K, having a Haring upper end to receive the horn H of the basin A, the coupling-ring 10, screwed upon the lateral branch 11, and the elastic ring 12 around the thimble K and within the coupling 10 to make a tight joint, substantially as set l'orth.

2. rPhe combination, with the horizontal waste-pipe C and vertical stand-pipe E, ofthe socket G, screwed n pon the exterior of the stand-pipe E, and having a flange resting upon the slab, and an inwardly-projecting pin, 17, the overflow-pipe and valve within the standpipe, the tubular cap P, screwed upon the eX- terior ofthe overflow-pipe and slotted for the reception of the piu 17, and the lock-nut 16 at the lower cud of the tubular cap P, substantially as and for the purposes set forth.

Signed by ine this 28th day of September, A. D. 1885.
